WebJan 30, 2015 · To investigate the molecular mechanisms underlying diapause induction, we used custom whole transcriptome microarrays to identify differences in gene expression following exposure to nondiapause (long days, 25 °C) and diapause-inducing (short days, 18 °C) environmental conditions. Using a two-way ANOVA, we identified 1130 genes that … WebNo sensitive instar was identified for diapause induction under alternated short- (L : D 11 : 13 h) and long-day (L : D 14 : 10 h) treatments at different larval stages. However, accumulative treatment of three instars and 10 d under short-day treatment was required for the induction of 50% larval diapause. All larvae entered diapause at 20°C ...

WebAdaptive grandmaternal thermal effect, wherein the grandmaternal thermal environment affects the induction of progeny diapause two generations later, has not been studied in any insect system. We have studied this effect in the parthenogenetic egg parasitoid Trichogramma telengai Sor. (Hymenoptera: … WebJan 1, 2024 · Abstract. The onion maggot, Delia antiqua, is a worldwide subterranean pest and can enter diapause during the summer and winter seasons.The molecular regulation of the ontogenesis transition remains largely unknown. Here we used high-throughput RNA sequencing to identify candidate genes and processes linked to summer diapause (SD) … ips laptop screen

WebThe rice stem borer, Chilo suppressalis, enters facultative diapause as fully grown larvae in response to short-day conditions during the autumn. Our results showed that the critical night length for diapause induction in C. suppressalis was between 10 h 22 min and 10h 45 min at 22, 25 and 28 degrees C, 11 h 18 min at 31 degrees C, and between ... Web1 day ago · In the context of global warming, populations of parasitoids from mild winter areas do not enter diapause anymore, as the temperature threshold for diapause induction is no longer reached [31]. In the parasitoid Meteorus trachynotus (Tortricidae) [32] , voltinism (i.e. the number of generations per year) increases in populations at low ...
